Fracture-dislocation at the thoracolumbar junction in an infant with locked vertebrae - A case report

Study Design. A retrospective, single-patient case report. Objectives. To report on a 9-month-old infant with fracture-dislocation at the thoracolumbar junction with locking of vertebral bodies, probably with incomplete neurologic injury and partial postoperative recovery. Summary of Background Data. Fracture-dislocation at the thoracolumbar junction is rare in infants, the upper cervical spine being the level usually affected. In-complete neurologic injury is uncommon after such a severe shear injury. Methods. The patient was followed through personal examination and chart review from initial presentation to 6 months after the injury. Results. Open reduction with posterior spinal fusion was followed by partial neurologic recovery and a stable spine over 6-month follow-up. Conclusions. Fracture-dislocation at the thoracolumbar junction is rare in infancy. This is probably due to unique anatomic and biomechanical features of the spine in infancy.
